Nifty 50 stock index jumped to its highest closing level since mid-January on Tuesday, driven by sharp gains in financials, while investors eyed US inflation data for cues on interest rates.

The Nifty 50 index was up 0.75 per cent at 18,070.05, while the S&P BSE Sensex rose 0.76 per cent to 60,571.08, both registering their fourth straight session of gains.

Emerging market peers, and broader stock markets too, traded higher as the dollar index weakened ahead of data that could show US inflation is peaking.

Meanwhile, persistent foreign investor purchases and weak oil prices aided gains in local stocks, analysts said.

"What is adding to the fizz has been the return of the FIIs (foreign institutional investors) into local shares over the past month or so and the falling US dollar index," said Shrikant Chouhan, head of equity research (retail) at Kotak Securities.
